I am rendering an image that is taking a REALLY long time. And the longer
the computer runs the higher the chances are of it crashing, thank you
Microsoft. So i was thinking.
Is there an easy way to render an image in small parts, saved in separate
files, which can the be easily put together to make a whole image. This way
if something happens during one of the renders, only a small part will have
to be redone.
If you know of any software or anyway i could do that, please post.
Thank you,
Boris.

I'm actually in the same situation right now for my IRTC surrealism image.
The image was too much for my machine to handle in one pass, so I broke it
up into 4 pieces and I'm running it on 2 machines. By my calculations, the
image as a whole will take 30+ days to render and I doubt it will be done by
the deadline.
Anyhow, here's what I did. 1600x1200 image, divided into 4 pieces of
1600x300. In the command line box at the top of the POV window (the one
right next to the resolution) I type in:
+sr0 +sc0 +er0.25 +ec1
sr being start row, sc is start column, er is end row, and ec is end column.
It's all in the docs if you need better explaining. Hopefully tht makes
sense.

might I suggest the +c command line option? 5.2.2.1.4 in the docs, comes in
real handy in the event of a computer crash.

What do you use to put the 4 pices back together perfectly?

If you're on Windows, just stop the render, close POV, and your computer if
you like.
When start POV again, go to menu>render>rerun>continue.
Make a copy of partially rendered image before, just for a safe. You will
able to read it in almost all image viewers.
Or you can do this with command line, oh sure.

I would think that its pretty hard to allign the many pices of an image
perfectly, pixel, by pixel, doing it by hand... In a regular image editor

It isn't hard if you have image editor which support layer blending modes,
like a Gimp or Photoshop, and, if pieces of image have a small overlaps.
Just set front layer to a difference mode. If overlapping area is black,
this means that you align this part.

You can render an image in pieces unless it has radiosity. Then you're in
trouble, with lots of manual work ahead to mix parts that don't have the
same overall light.
Images without radiosity can be rendered in networks or just over sessions.
I rarely do this, but then I align the parts manually in PaintShopPro.
You can also try this nifty little application:

I couldn't get it to work, last time I tried but I'm sure it was my fault..
I should probably try again, since I have use for it.

Hugo

Sorry for dealyed response, I have been moving into a new place and just got
my internet acces back today. As far as reconstructing your image, you can
do it very easily in any paint program. If each piece picks up where the
last one left off, you simply copy and paste them. There might be a more
elegant approach, but that's all I do.
